Have you checked the bulbs? Bulbs can short out and flow fuses, since the rear turn and brake lamps share a filament, I would pull the front bulbs and try again. And welcome to the forum.

Are you sure fuse 2.7 does not go to the headlight switch?

Or did you mean fuse 2.27? (this fuse controls the circuits you describe)

The 2.27 fuse is blowing, NOT the 2.7 ?
